Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 32 points:

(1,2,7,16,5,10,6,9)(3,11,15,8,13,14,12,4);(6,7)(9,16)(11,14)(12,15)(17,18,21,24)(19,25,27,32)(20,28,30,23)(22,29,31,26);(1,3)(2,8)(4,10)(5,13)(6,15)(7,12)(9,14)(11,16)(17,19,21,27)(18,22,24,31)(20,29,30,26)(23,32,28,25);(1,4,5,8)(2,3,10,13)(6,11,7,14)(9,15,16,12)
